MITRE ATT&CK
T1059.005 Visual Basic
The sample is a Microsoft Word document containing VBA macros, specifically a Document_Open macro, which is a common technique for initiating malicious activity. The ClamAV detection 'Doc.Trojan.Thus-8' further indicates malicious intent. Although no specific malicious URLs or scripts were extracted, the presence of the Document_Open macro strongly suggests the document is designed to execute arbitrary code when opened.
Heuristics 4
-
ClamAV detection on extracted artifact critical EXTRACTED_FILE_CLAMAVClamAV flagged at least one file extracted from inside this sample. Even when the wrapping document carries no AV detection of its own, a hit on the carved artifact is a strong indicator the sample is a delivery vehicle.
-
Document_Open macro high OLE_VBA_DOCOPENDocument_Open macro
-
VBA macros detected medium OLE_VBA_MACROSDocument contains VBA macro code
-
Embedded URL info EMBEDDED_URLOne or more URLs were extracted from the document.
